PORTERVILLE, Calif. (AP) — A California Indian tribe said Tuesday it will hold candlelight vigils for the rest of the week to honor five family members who were slain over the weekend.

Tribal Chairman Neil Peyron of the Tule River Indian Reservation called the killings "one of the most horrific losses" ever faced by the tribe that teaches its members that love for family is above all.

Authorities suspect Hector Celaya killed his 8-year-old daughter Alyssa Celaya, his mother, her two brothers, and wounded his young son and daughter on Saturday. Hours later Hector Celaya was shot during an exchange of gunfire with deputies and died at a hospital.

Andrew Celaya, 6, remained in critical condition Tuesday at Community Medical Center in Fresno. The condition of his sister, Linea Celaya, 5, was upgraded to fair on Tuesday afternoon.

No motive has been established, though police said Hector Celaya, a former custodian at the tribe's Eagle Mountain Casino, had been involved in custody disputes with the mother of his children.

The mother, Lindsay Ann Burrough, could not be immediately reached for comment Tuesday, but photos and comments on her Facebook page revolve around her children. She said in November that Alyssa was outgoing and "always has to dance" and sing and "be tha BOSS n tha center of attention almost all the time..."

Andrew, she wrote, is a handsome "mommas boi" who loves his grandmother.

The family has declined to comment to The Associated Press.

"I'm just sad, too sad," said Vincent Burrough, who answered the family's home phone on Tuesday. His relation to Lindsay Burrough was unclear.

The violence has shaken this peace-preaching tribe.

Murder is unheard of on the reservation, said Mike Blain, chief of the Tule reservation's small police department. He was at a loss to say what prompted the violence.

Peyron said in the statement that the candlelight vigil will begin the healing process.

Court records show that Celaya, a former custodian at the reservation casino, had spent time in jail in 2008 after pleading no contest to an assault and battery charge, the Fresno Bee reported.

He was facing a possible return to jail after recent arrests for investigation of drunken driving and drug use, the newspaper reported (http://bit.ly/S135Pv ) Tuesday.

Blain said his department would work to aid the healing of the tightknit community of about 800 people.

"We needed to go back and find what brought us to this. Did we miss something? Did the community or family miss something?" he said from his office in a doublewide modular home.

Irene Celaya, 60, and her brother Francisco "Frank" Moreno, 61, were killed in a travel trailer at the compound where the family lived. Bernard Moreno, 53, was found slain in an outbuilding set up as a bedroom. Continued...
